VS070QS-1618MDM1 Integrated Machine Temperature autotuning PID
202403 (V1.0) 43
Before executing the above control modes, you need to confirm whether the
sampling cycle, control cycle, temperature upper and lower limits and control
modes are applicable to the heating requirements of the specific control object.
If not, please modify these parameters before heating. The sampling cycle shall
be set according to the heating object, and it is generally set to 200ms. The
temperature system changes slowly, so the scanning cycle shall not be too
small. Considering the service life of the relay, the control cycle shall be
≥2000ms.
The average sampling times of analog input channels and analog output
channels shall not be too large or too small. If it is too small, the temperature
jump on a small scale may occur, which is unfavorable to autotuning. If it is too
large, the temperature change will lag behind the actual temperature, which is
unfavorable to temperature control. it is recommended to set the average
sampling times≥2.
If S+16 (high-speed PWM enabling bit) is 0, the output is normal PWM and the
unit of the output relay switching cycle is ms. If high-speed PWM speed is
required, enable S+16 (high-speed PWM enabling bit) and configure the output
bits as Y0–Y3, then the unit of the relay switching cycle will be changed from ms
to μs.
